This study aimed to evaluate the morphological, phytochemical, and essential oils (EOs) variations among nine Iranian <em>Pimpinella deverroides</em> populations (<em>PDPs</em>). Significant variation was observed in morphological traits, as well as in the total contents of phenols, anthocyanins, carotenoids, and chlorophyll. Among the studied populations, <em>PDP</em>4 exhibited superior performance in terms of plant height (108 ± 1.15 cm), number of umbellate (212.3 ± 4.05), plant fresh weight (1048 ± 5.77 g), and plant dry weight (592 ± 4.61 g). The EOs and phenolic acids extracted from air-dried aerial parts were analyzed using chromatographic techniques including GC, GC/MS and HPLC. The highest contents of rutin (2.57 ± 0.035 mg/g DW) and chlorogenic acid (12.43 ± 0.057 mg/g DW) were found in <em>PDP</em>3 and <em>PDP</em>5, respectively. In total, thirty-one compounds representing 90.34–96.73 % of the total EOs composition were identified, with twenty-two compounds shared across all populations. Spathulenol (2.07–17.31 %), γ-eudesmol (1.63–11.91 %), oleic acid (5.02–10.73 %), and δ-cadinene (1.00–7.73 %) were the major compounds identified in the EOs. Oxygenated sesquiterpenes (28.71–47.36 %) and hydrocarbon sesquiterpenes (21.78–35.45 %) were the main groups of compounds in the studied EOs. Three main chemotypes were found to be Chemotype I (spiro[4.4] nona-1,6-diene, valernanone), Chemotype II (oleic acid/spathulenol) and Chemotype III (δ-cadinene, δ-elemene).

Many plant phytochemicals have been identified in this plant, including (Z)-ligustilide, (Z)-butylidene phthalide, (E)-butylidene phthalide, and others, which are the principal cause of its medicinal efficacy. The plant possesses various biological properties, such as antioxidant, antibacterial, antifungal, broncho-relaxant, anticancer, and neuroprotective actions that have been supported by multiple studies. The primary components of this plant with pharmacological relevance are its roots, which produce more essential oil than other plant parts. Its roots are primarily used to treat digestive diseases as they have carminative properties. Since it has high essential oil content, this plant has become valuable to the cosmetics and pharmaceutical industries.
